the blocks are symmetrical, so for most of them, you only do need one section and just trace it four times. I'm thinking of doing that for the hand one so I have larger pieces to work with.
I just made copies and could get the full height and about 3/4 of the width, so that worked to get enough of each pattern to work with. I used a default on my copier (141%) and I think I'm going to end up with closer to 9.5" blocks. But that is fine as I can cut WOF into four and have enough wiggle room for squaring up. My pattern is going to end up closer to the edge of the block than as designed to make this work. Should have stopped and checked before I copied all the pages at that % LOL!!
That's one thing to keep in mind when enlarging - if you go large enough to only get 3 blocks WOF, you are going to need more fabric for the background.
